Ukuqhekeka! Amandla aphezulu ehlabathi 3 μm μm i-infraredI-Febtosecond Fiber Laser

I-Fiber LaserUkufezekisa iziphumo eziphakathi eziphakathi, inyathelo lokuqala kukukhetha i-fiber matrix efanelekileyo. Kwi-Inrad-Inrad Fiber fiber Lasers, i-Matrix yeglasi ye-biber yeyona nto ixhaphakileyo ye-fiber matrix enelahleko ephantsi kakhulu, amandla omatshini onokuthenjwa kunye nozinzo olugqibeleleyo. Nangona kunjalo, ngenxa ye-Phonon ephezulu (i-1150 cm-1), i-fiber ye-piber ayinakusetyenziselwa ukuhanjiswa okuphakathi. Ukuze kufezekiswe ukusweleka kwelahleko esezantsi e-Infrared Laser, kufuneka sikhethe kwakhona ezinye izinto ze-fiber ze-fiber kunye namandla asezantsi e-Phonon, ezinjenge-sulfide matrix okanye i-rulrix yeglasi yeglasi. I-fiber ye-fiber inamandla aphantsi (malunga ne-350 cm-1 cm-1), kodwa inengxaki yokuba ukugxininiswa kwe-dexing akunakunyuswa, ngoko akulunganga ukusetyenziswa njenge-fiber yokufumana i-larred i-leser ye-leser. Nangona i-fluoride glass substicar inomgangatho onqabileyo we-Phonon (550 cm-1) kuneglasi ye-Sulfide, inokufikelela kwilahleko ye-Sulfide, inokufikelela kwilahleko yelahleko ye-intermid enama-4 μm. Eyona nto ibaluleke kakhulu, iGlooride Glass Substale inokufikelela kwi-ion enqabileyo ye-ion, enokubonelela nge-inter eqondakalayo ye-laser efihliweyo, umzekelo, eyona nto ikhulisayo ye-Er3 + ikwazi ukufikelela kwi-10 mol. Ke ngoko, i-fluoride matrix matrix yeyona nto ifanelekileyo ye-firber matrix ye-fiber fiber lars.

Kutshanje, iqela likaNjingalwazi RuangChen kunye noProfesalo Guo Chunyu kwiYunivesithi yaseShenzhen iphuhlise i-phytosencond yamandla e-phytosePubse Fiber LaserIqulathwe yi-2.8μm itshixiwe i-ER: I-Zblan Fiber Oscillator, i-Pot-Mode-Pook Er: I-Zblan Fiber Prepie kunye neNdawo enkulu ye-Er-fiber er
Ngokusekwe kwi-consorions kunye ne-Interlisotion ye-Inrad Pulse-i-Inrad Pulse elawulwa ngurhulumente we-polarication kunye neteknoloji yokulawula i-piber ye-piber, edityanisiweyo ye-Istra-i-orting ye-Artra-i-orting ye-148w kunye nobubanzi be-148 fs. Ingxelo yeHlabathi yamandla aphezulu elona nqanaba liphezulu lifezekiswe yile qela lophando lahlaziywa.

Umzobo 1 wamabakhiwo umzobo we-ER: I-Zblan Fiber Laser esekwe kulwakhiwo lweMopa
Ubume beI-Febtosecond LaserInkqubo iboniswe kumzobo 1. Imowudi enye i-Erd Er: I-Zblan Fiber ye-3.1 ubude yayisetyenziswa njenge-fiber ye-7 μ (na = 0.12). Kwi-amplifier ephambili, i-fibe yendlela enkulu ye-Er: I-Zblan Fiber ngobude obuyi-4 m yayisetyenziswa njenge-fiber eyi-6 μ (na = 0.12). I-core enkulu ye-core yenza i-fiber ye-fiber inamahlalo ane-nonline ye-nonline kwaye inokumelana namandla encopho ephezulu kunye nokukhupha amandla amakhulu epulse. Zombini iziphelo zefayibha ye-fiber ifudukela kwi-alf3 ye-terminal cap.
